Summary: FYI: For those of you who "do not" know anything about laptop RAMs, read on please... RAMs for laptops are called SO-DIMM. They have 3 generations, but I am not going to talk about the very old generations. Just these 3 should be just about what people are "still" using.
Summary: So I decided I was going to update my wife's 2010 MacBook Pro. I went and bought a new SSD hard drive and these guys to upgrade the RAM while I was at it. After having done this several times for friends/family laptops, I didn't really doubt what I was doing.
Summary: The low rating is for my situation as other users might have success with it. I upgraded a 2009 Mac Mini with a Kingston 240 gb SSD and this RAM kit. My Mini kept shutting down every time I did Youtube or XBMC. So, I started to look for the obvious.
